Plain English summary of protocol
Background and study aims
Free gingival grafts – when healthy tissue from the roof of your mouth is attached to your teeth where the root is exposed can prevent any further loss of gum tissue and it can help with sensitivity.
The spice turmeric contains a substance called curcumin, which has long been used in Asian medicine and is linked to health benefits.
This study aims to evaluate the therapeutic effect of curcumin extract and comparing using it or gingival dressing after grafting surgery.
Who can participate?
Healthy adults aged 18 - 45 years who are non-smokers
What does the study involve?
Piece of gum will be grafted and sutured for each group. One group will receive curcumin gel and the other will receive gingival dressing. The size of the grafts, their healing and the patient's pain will be assessed afterwards.
What are the possible benefits and risks of participating?
Both are safe and should not cause any additional risks, other than those involved in the gum grafting procedure. All participants will receive the same treatment.

| Scientific title | Evaluation of the usage of extracted curcumin in the healing of free gingival graft and donor site palatal wound |
| Study objectives | To test the therapeutic effect of curcumin extracted gel, and comparing it to gingival dressing after free gingival graft surgery |
| Ethics approval(s) | Approved 09/10/2020, Ethics Committee- Dental College- Damascus University (Mazzeh Highway, Damascus, Syria; +963 1133923486; sr.srd@damasuniv.edu.sy), ref: no.3889 |
| Health condition(s) or problem(s) studied | Free gingival (gum) treatment for absence or insufficiency of attached gingiva |
| Intervention | All participants undergo free gingival graft surgery In the test group, we will apply curcumin gel in the donor and recipient site for 7 days after surgery. In the control group, we will apply gingival dressing in the donor and recipient site. The size of the grafts, their healing and the patient's pain will be assessed afterwards for 3 months. Randomization method: flipping a coin. |
| Intervention type | Supplement |
| Primary outcome measure(s) |
Shrinkage of the graft assessed using at 2 months, 3 months and 6 months. A standard sizing template of known size is placed beside the graft and digital photographs are taken. Software is used to calculate the size of the graft by comparing it with the template in the images |
| Key secondary outcome measure(s) |
1. Shrinkage of the graft assessed using at 2 months, 3 months and 1. Recipient site healing assessed using the modified early-wound healing index (MEHI) at 1 week, 2 weeks, 1 month and 2 months |
